Absolute Optical Shaft Rotary Encoder • Built-in mechanical gear module (Mechanical multi-turn) • Built-in electronic memory chip (Electronic multi-turn)） • Multiple electrical interfaces, uniform mechanical dimensions • Simple installation，Large mechanical tolerance

Magetic rotary encoder is one type of new angle or displacement measuring device. Magnetic reluctance or hall elements could sense the angle or motion value of the magnetic material. When there is any changes on the magnetic material's angle or motion, the resistance and voltage will change also. Through enlarging the variable value, rotary magnetic absolute encoder can judge the angular and position information.
